1. An apparatus comprising: a transmitter; a receiver; and a processor coupled to the transmitter and the receiver, wherein the apparatus comprises communication settings not associated with a user, and wherein the processor is configured to: receive user information associated with the user; cause the user information to be transmitted via the transmitter to a profile server for authentication; receive a personal identification number (PIN) from the user and cause the transmitter to transmit the PIN to the profile server for authentication; receive user profile data associated with the user from the profile server; and update the communication settings to include the user profile data; and an authentication sensor coupled to the processor, wherein the user information is received by the processor from a user identifier (UI) via the authentication sensor, wherein the UI comprises a mobile telephone, wherein the authentication sensor is configured to receive biometric data from the user, wherein the transmitter is configured to transmit the biometric data to the profile server for authentication, wherein the apparatus further comprises a telephone, wherein the user profile data is associated with a user telephone number, wherein updating the communication settings to include the user profile data allows incoming telephone calls placed to the user telephone number to be routed to and received by the apparatus for presentation to the user, wherein the receiver is configured to receive an auto logout message from the profile server when the user logs into a remote telephone not attached to the apparatus, and wherein the processor is further configured to prevent telephone line extension reassignment to a second telephone number associated with a second user while a first user is logged in to the apparatus based on the user profile data.

2. The apparatus of claim 1 , wherein the authentication sensor comprises an Radio Frequency Identification (RFID) sensor.

3. The apparatus of claim 1 , wherein the authentication sensor comprises a near field communication (NFC) sensor.

4. The apparatus of claim 3 , wherein the user information comprises a username but not a password.
